When creating a tab, the list of tabs moves to the end. Exasperate

not working on 95.0.2

Unfortunately, this doesn't work for the only purpose I downloaded it for: opening new tabs as "first", on the left of the window, before all other tabs.

(The other functions of the add-on seem to work, though, under a cursory test. YMMV.)

This not work when close tab with gesture.

-> Tab Open/Close Control
Mince... ça n'a fonctionné qu'une seule fois à l'installation...

Je l'avais installé pour, lorsque que je ferme un Tab/onglet, FF revenienne au Tab de gauche et non plus à celui de droite.

Du coup, je désinstalle

Open tab on right works, but close tab go back to left is not working on FF83, instead it just going back to last active tab after closing.

Use this addon instead... "Activate Left Tab On Close"

open tab on right works, but close tab go back to left is not working on FF77.01, instead it just going back to last active tab after closing.

To open new tab as First Tab doesn't seem to work, it opens as Last Tab, same behaviour as open as Last Tab. Otherwise most things else seem to work great! I initially wanted the open as First Tab, but will try "open to the Left Side of Active" for a while now, think it will be perfect actually! Firefox version: 76.0.1 (64-bit)

Awesome plugin, very needed! Missed this a long time.

Doesn't work as expected. After closing a tab any other tab can become active despite of the addon settings.

Tab Open/Close Control does move the tab row at the top a bit to the left while opening from links, this is not useful.

ok, you must also do this:
about:config -> browser.tabs.insertRelatedAfterCurrent -> true
about:config -> browser.tabs.selectOwnerOnClose -> true
